0.8y+0.25= -0.4
Solve for y
Answer:
y = -13/16
Step-by-step explanation:
Given:
0.8y+0.25= -0.4
To Find:
Solve for y
Solution:
Multiply both sides by 100
[tex]0.8y\cdot \:100+0.25\cdot \:100=-0.4\cdot \:100[/tex]
Simplify
[tex]80y+25=-40[/tex]
Subtract 25 from both sides
[tex]80y+25-25=-40-25[/tex]
Simplify
[tex]80y=-65[/tex]
Divide both sides by 80
[tex]\frac{80y}{80}=\frac{-65}{80}[/tex]
Simplify
[tex]y=-\frac{13}{16}[/tex]
Thus, y = -13/16
or in decimal form it equal y = -0.8125

Two angles of a quadrilateral measure 200° and 50°. The other two angles are in a ratio of 4:7. What are the measures of those two angles?
Answer:
all angles will be 200, 50 , 40 and 70 - hope this helped :)
Step-by-step explanation:
everything equals to 360 after added together
360 - 250 = 110
110 divided by 11 = 10
4:7 (x 10)
40:70
the other angels will be 40 and 70
In a right triangle, the side opposite angle φ has a length of 29.0 meters, the side adjacent to angle φ has a length of 49.5 meters, and the hypotenuse has a length of 57.4 meters. What is the value of cot(φ)?

1.707
0.586
1.160
The right triangle with sides 29m, 49.5m and 57.4 m has the value of cot φ as 1.707
What is a right angle triangle?A right angle triangle has one of its angles as 90 degrees.
Therefore, it has an opposite, adjacent and hypotenuse side depending on the angle.
oposite side = 29 m
adjacent side = 49.5 m
hypotenuse side = 57.4 m
Therefore,
cot φ = 1 / tan φ
Hence,
tan φ = opposite / adjacent
Therefore,
cot φ = adjacent / opposite
cot φ = 49.5 / 29
cot φ = 1.70689655172
cot φ = 1.707

A geometrical series have a constant ratio. The value of r is 4, while the value of a1 is 0.25 and the value of n is 5.
What is geometrical series?A geometrical series is a series of numbers where the quotient of any two consecutive terms of the series is constant.
The given series is a geometrical series which is given as, 0.25, 1, 4, 16, 64.
Now the value of r is the ratio of any two consecutive terms of the geometrical series therefore, the value of r can be written as,
[tex]r = \dfrac{1}{0.25}=4[/tex]
The a1 of a geometrical series is the first term of the series, therefore, the value of a1 can be written as,
a1 = 0.25
The n is the number of terms in a geometrical series, therefore, the value of n can be written as
n = 5
Hence, the value of r is 4, while the value of a1 is 0.25 and the value of n is 5.

Given:
slope = m = 3/2point = (x1,y1) = (-6,6)Point-Slope:
[tex]\displaystyle \large{y-y_1=m(x-x_1)}[/tex]
Substitute m = 3/2, x1 = -6 and y1 = 6:

Answer:
214°
Step-by-step explanation:
The external angle (marked 34°) is equal to half the difference of the arcs ACB and AB.
34° = 1/2(ACB -AB)
Together, the two arcs form a complete circle of 360°, so we have ...
34° = 1/2(ACB -(360° -ACB)) = 1/2(2ACB -360°)
34° = ACB -180° . . . . . . . . . . . . simplify
180° +34° = ACB = 214° . . . . . add 180°
The measure of arc ACB is 214°.

The dues in a neighborhood increased from $24 per month to $30 per month. Find the percent of increase.
Answer:
25%
Step-by-step explanation:
Think about it like this: $24 multiplied by how much equals $30?
This in equation form would be [tex]24x=30[/tex]
To solve for x, divide both sides by 24: [tex]x=30/24[/tex] or [tex]x=5/4[/tex]
5/4 in percentage form would be 125%, so the dues increased by 25%

The volume of the large sphere shown in the image is, 1/27 times the volume of the small sphere.
What is of volume of sphere?Volume of sphere is the amount of quantity, which is obtained by the it in the 3 dimensional space.
The volume of the sphere can be given as,
